Generic script to recursively cd into directories and git pull

Hi all,

I'm trying to write a script to recursively cd into my Git projects and pull them, and will later expand it to build my projects as well.

I'm having a bit of trouble with my current script, as I want to supply a command line argument to tell it which branch to check out. I can hard code it to check out a specific branch but it's failing to take in my arguments.

My current script is:

Code:

#!/bin/bash
BRANCH=$2
echo "Checking out branch $BRANCH"
find . -type d -name .git -exec sh -c 'cd "$1"/../ && pwd && git checkout $BRANCH && git pull; echo "Branch being passed in: $BRANCH' _ '{}' "$BRANCH" \;

A snippet of the output when I run it from the top level of a directory containing many git projects is:

Code:

cows@Whiskey:~/windows/Workspace/git-projects/my-project$ ~/gitupdate.sh _ development
Checking out branch development
/home/cows/windows/Workspace/git-projects/my-project
Your branch is up-to-date with 'origin/master'.
Already up-to-date.
Branch being passed in:

So it looks like the -exec part of the script isn't pulling in my arguments and is just defaulting to the current branch. Any ideas on how to resolve this will be much appreciated. I don't mind if I have to rework how the script works entirely.

The recursive part of the script seems to work fine. If I run the script from ~/windows/Workspace/git-projects, it correctly descends into my-project, my-project-2, my-other-project, etc.

Thanks in advance for any help.

Edit: Fixed formatting. Sorry mods!

GIT-SH-I18N(1)							    Git Manual							    GIT-SH-I18N(1)

NAME

       git-sh-i18n - Git's i18n setup code for shell scripts

SYNOPSIS

       . "$(git --exec-path)/git-sh-i18n"

DESCRIPTION

       This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish
       scripts and/or are writing new ones.

       The 'git sh-i18n scriptlet is designed to be sourced (using .) by Git's porcelain programs implemented in shell script. It provides
       wrappers for the GNU gettext and eval_gettext functions accessible through the gettext.sh script, and provides pass-through fallbacks on
       systems without GNU gettext.

FUNCTIONS

       gettext
	   Currently a dummy fall-through function implemented as a wrapper around printf(1). Will be replaced by a real gettext implementation in
	   a later version.

       eval_gettext
	   Currently a dummy fall-through function implemented as a wrapper around printf(1) with variables expanded by the git-sh-
	   i18n--envsubst(1) helper. Will be replaced by a real gettext implementation in a later version.
